Ondrej: Thanks a lot indeed! These documents seem to have the essential interface details all covered, except for Fast-20 SCSI adapters, which I guess are a minor modification from the software's point of view. Khalid: I have skimmed over these documents and I infer 24-bit addressing can be verified with any MultiMaster adapter, including ones that do have 32-bit addressing implemented, by using the legacy Initialize Mailbox HBA command. That could be used to stop Christoph's recent changes for older adapter support removal and replace them with proper fixes for whatever has become broken. Is that something you'd be willing as the driver's maintainer to look into, or shall I? Maciej
